Laser consolidation is an effective way for aircraft part manufacturing and repair. The traditional open-loop laser process relies heavily on an operator?s expertise in order to establish a production process. T...

Although laser cladding was developed thirty years ago, it has only been in the last ten years that research groups and companies have begun to exploit this technology to produce fully dense, near-net shape components with metals through techniques such as DMD, DMF, Laser Consolidation, or LENS. In order to produce components with fine features, it is necessary to provide prop...

This paper investigates deep engraving of steel and aluminium by laser. By examination of laser and scanner parameters an optimal balance between feature quality and processing speed is achieved. Material removal rates of up to 20mm3/min for steel and 40mm3/min for aluminium are demonstrated up to a maximum e...

Laser welding has been widely accepted in many industries. Commercial systems are now available to laser weld steel coils end-to-end for continuous processing in steel mills. These systems compete with more traditional flash butt and resistance seam welding systems. This paper will describe the technical requirements for a coil joining weld, in terms of welding time and weld properties, and compare the c...

How Laser Production Systems are Being Employed to Effectively Machine, Weld and Repair Turbine Engine ComponentsAuthors:John Stackhouse, Winbro Group Technologies; Coalville UKPresented at ICALEO 2005

Turbine engine manufacturers are employing Laser Systems to drill,ablate, cut, weld, clad and mark critical components used in both aircraft and industrial gas turbines. Details of these techniques are discussed and explanations of the various Technology Modules such as DOF (drilling-on-the-fl ), probing, SPC and breakthrough detection are given. Turnkey solutions employing Robotized loading and unloading of workpieces are discussed. The use of YAG, Q-switched, CO2 and other Laser power sour...

Robot-based remote welding with solid-state lasers increasingly becomes an issue for automotive industry due to low process costs in comparison to spot welding or conventional laser welding. When talking about remote welding, very often the necessity of high beam qualities is emphasized, which can so far only be delivered by diode-pumped Yb:YAG disc and fibre lasers. However, industrially qualified and widely-used today are Nd:YAG rod laser...

Corrugated core sandwich panels comprise a corrugation sheet between two thin face sheets. The significant features of such panels are their high strength and stiffness to weight ratios; however, the stiffness is substantially less perpendicular the directio...

Welding and brazing are well known joining processes applied in many industries for decades. Using a laser as the principal source of energy to replace the oxy-fuel or arc processes is somewhat new. Although basic welding engineering principles must be carefully followed in order to achieve quality welds, they have sometimes been o...
